Advice on kiltmaking supplies?

[Prester John]

"Practice Tartan" is actually a misnomer. You can practice on any Tartan fabric. Until you actually cut away the pleats in the Fell any stitches you put in can be ripped out and re-done at your leisure.
My advice is to find the best fabric you can afford. Go ahead and stitch it up practicing on sewing the Fell until you get it perfect. Rip out if necessary and re-stitch till you like the result. Then continue with the rest of the construction.
When you are done you have a full first quality Kilt.

Thanks for that most EXCELLENT advice!

May God richly bless you!
